This move allows Rak-Sakyi to gain experience in the Super Lig, Turkey's top football league.
Last season, Rak-Sakyi impressed while on loan with Charlton Athletic, scoring goals and helping the team.
He then moved to Sheffield United, where he scored seven times in 36 matches, but unfortunately, the team missed out on promotion.
Rak-Sakyi, now 22 years old, has moved to Caykur Rizespor on-loan without the option to buy the player.
This transfer marks a new chapter in Rak-Sakyi's career, which began when he joined Crystal Palace from Chelsea in 2019.
